HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 744,482, dated November 17, 1903.

Application filed May 6, 1903. Serial No. 155,812. (No model.)

To all whom it may concern:

Be it known that I, ALBERT CARR, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Horseshoes, of which the following is a specification.-

My invention relates to a new and useful improvement in horseshoes, and has for its object to provide a two-part horseshoe horizontally divided, the part which is attached to the hoof designed to be used in summer and ordinary weather as an ordinary smooth shoe and the detachable part being provided upon its under surface with sharpened projections which may be attached to the otherpart of the shoe, so, that the horse may be rough shod.

With these ends in viewthis invention consists in the details ofconstruction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which Figure 1 is a bottom plan view of a horseshoe made according to my invention; Fig. 2, a vertical sectionthrough-a horseshoe made according to my invention; Fig. 3, a plan view of the inner face of the detachable portion of the horseshoe; Fig. 4, a bottom plan view of the portion of the shoe designed to be attached to the hoof; Fig. 5, a section taken on the line 5 5 of Fig. 1.

It is a well-known fact that in the summertime and under all ordinary conditions it is desirable that horses shall, be shod with a light shoe smooth upon the under side; but in winter, when the streets are slippery from ice and snow, it is necessary to have the horse rough shod-that is, providedwith' sharpened shoesand to accomplish. this change it is necessary to remove the smooth shoes and substitute a new pair of sharpened shoes.

My invention is for the purpose of providing a shoe which may be changed by'any unskilled person from a smooth to a sharpened shoe, and vice versa, within a short space of time.

. A represents that portion of the shoe which Y is secured to the hoof of the horse. This portion A is provided upon its under side with V a groove B, and in this groove arranged at intervals are thickened portions B.

0 represents the detachable portion of the a cut-away portions D, and screw-threaded holes G are formed in the portion A of the shoe through the thickened portion B; but these holesG do not pass entirely through the portion A. The two parts of the shoe are designed to be secured together by screws H, which pass upward through the portion 0 and are threaded in the portion A. The heads of the screws H will be above the lower surface of the portion 0, so as not to receive any of the wear. Thus it will be seen that by removing the portion 0 of the shoe the portion A can be used as an ordinary smooth shoe; but when occasion demands'the sharpened portion 0 of the shoe can be attached in a very short time, and this can be carried in the vehicle, so as to be convenient at any time.

Of course I do not wish to be limited to the exact means here shown for securing the two portions together, as my main idea lies in making a two-part shoe, one smooth and the other rough, and providing means for securing these two parts together. ThereforeI do not wish to be limited to the exact construction here shown, as slight modificationscould be made without departing from the spirit of the invention.

Having thus fully described my invention, what I claim as new and useful is A horseshoe composed of two parts divided horizontally, the upper part designed to be ICO secured to the hoof of the horse in the ordinary manner, the lower face of this upper part being provided with a concentric groove 15, raised portions B provided at intervals within the groove, screw threaded holes formed in these raised portions from the bottom upward, but not extending through the shoe, the second part of the horseshoe being provided upon its upper face with a concentric tongue adapted to fit in the groove of the other part, said tongue being cut away at intervals to receive the raised portions B of the other part, said last-named part being provided with holes formed entirely through the same and adapted to register with the
